Title: Improvements in Apparatus for Ascertaining the Colour and Density of Photographic Negatives and other Bodies.
Inventor: DAWSON JOHN WILLIAM
Filed: 1900-09-21
Granted: 1901-03-16
Abstract: 16,813. Dawson, J. W. Sept. 21. Exposures, determining ; printing ; photometers a n d actinometers. - Relates to an instrument for determining the printing - value of negatives, for ascertaining the density and colour of other bodies, and capable of being used as a photometer with a standard source of light. The negative B to be examined is placed in a slot in the back of a box 1. The light passing through the negative at the aperture 4 falls on the ground glass 14, and is examined at the aperture 12. The light on the ground glass opposite the aperture 13 is adjusted as to density and colour until it corresponds exactly with the light at 12. The density is adjusted by turning the disc 7 until one of several apertures of different sizes is brought in line with the aperture 5 by which the light enters. The colour is adjusted by another disc 8, having apertures of the same size, but covered with tints of known actinic values. A lens 16 is used to converge the light on the screen 14. In one modification, the rays of light from 4 and 5 are brought close together by reflectors. In another modification, the density of the light at 13 is varied by adjusting a single aperture at different distances. The numbers read off from the edges of the two discs or other arrangements give the printing-value of the negative.

Granted: 1901-05-18
Abstract: 5778. Powell, J. B. March 19. Phonographs.-Relates to return motions for the reproducers of phonographs and similar machines. Fig. 1 shows a plan, in which the cylinder shaft is geared by wheels G, F with a return screw E.

Granted: 1901-10-05
Abstract: 7473. Josephy, G. April 11. Ring and traveller frames; rollers and roller heads; twist-tubes and like twisters; spindle apparatus.-The invention is specially applicable to machines for spinning short staple wool &c. The top rollers of the front set are made in short lengths, one for each thread, which is guided to the nip of the rollers by a twist tube, Fig. 3. The twist tube has a pair of guiding-projections at the end at which the thread enters, and at the other has a half cut-away conical point 9 terminating in a needle 10, which projects close to the nip of the rollers. The tubes are mounted on pivoted brackets, which are connected together by an adjustable rod, so that the tubes may be adjusted with regard to the line of nip of the rollers. The traveller consists of a piece of wire bent into the form shown in Figs. 4 and 6, the end loop 12 being passed through eyes in a plate 14, which runs round a channel 15 in the two parts of the ring, and allows the traveller to move outwards and inwards with the varying diameter of the cop.

Title: Improved Reversing Gear for Compound Steam Engines
Inventor: IMRAY OLIVER
Filed: 1901-04-17
Granted: 1902-01-30
Abstract: 7898. Imray, O., [Henschel & S÷hn]. April 17. Reversing.-Relates to reversing gear for compound engines, in which it is desired that the valve gear of both high and low pressure cylinders shall be simultaneously reversed, while the grade of expansion in the low-pressure cylinder is kept constant whatever the grade of expansion in the high-pressure cylinder. As shown in Figs. 1 and 2, an ordinary hand screw gear is provided for adjusting the expansion in, and reversing, the high-pressure cylinder, and an air-pressure or steam cylinder c is provided for reversing the low-pressure cylinder. The piston in this cylinder acts on a lever h, first withdrawing a latch by which it is held at either end of the sector l and then pushing it over to the opposite end. The admission and exhaust of fluid under pressure to the cylinder c is controlled by a four-way cock to which are connected the pipes b, b<1>, b<2>, b<3>. This cock is actuated by a pin d carried on the nut of the hand reversing- gear.

Title: Improvements in Hydraulic Brake-mechanism for Railway and like Vehicles.
Inventor: NEAL JAMES HENRY
Filed: 1901-06-04
Granted: 1901-08-24
Abstract: 11,410. Neal, J. H. June 4. Brakes.-In a hydraulic car brake, shown in plan in Fig. 1, a pump a, driven by the car axle b, is connected by pipes c, d to the inlet and outlet ports e, f, Figs. 6 and 8, of a valve casing g attached to the brake cylinder h having two pistons i, j, the rods k, l of which are connected to the ordinary brake levers m. The valve casing g contains a cylinder o having a piston valve p controlling a passage s, which connects this cylinder with the space into which the outlet port opens and communicates by a passage 60 with the space between the pistons. This cylinder also communicates by a passage q with the inlet port, which opens into a passage 12 leading to both ends of the brake cylinder h. When the valve p is open, the oil or other liquid will circulate freely, while, when this valve is closed, the oil &c. is forced behind the pistons, and the brakes are applied, the pressure being gradually relieved as the vehicle stops. The valve rod 13 is pivoted to levers 14, 15, the latter being connected to a lever 26. The levers 14, 26 are connected by pins and slots to eccentricrods 21, 29 operated to apply the brakes by handles 35 on the eccentric shafts 24 having brake chains 25, the rods being returned to their initial positions by springs 40, 41. To avoid waste of oil, the piston-rods pass through boxes 45 having perforations 46 opening into annular chambers 47 connected by irregular passages with the valve cylinder o.

Title: An Improved Combined Picture Exhibiting Machine and Sound Reproducing Device.
Inventor: MATTHEWS HAROLD CLARK
Filed: 1901-07-16
Granted: 1902-01-02
Abstract: 14,479. Matthews, H. C. July 16. Stereoscopes.-Relates to the combination with a phonograph of a number of stereoscopic pictures which are automatically and appropriately presented to the eye of the observer during the speaking of the phonograph. The pictures 11, Fig. 5, arranged like the leaves of a book, are secured in a frame 26 on a shaft 27 to which a parallel rod 50 is attached. The pictures are held in a raised position by a hook 13 on a rod 10 secured to the traveller 15, which carries the diaphragm holder 6. The edge of each picture is notched in such a way that at the appropriate time the hook 13 comes opposite to the notch and allows the picture to fall. Fig. 5 shows the parts of the apparatus as the reproducer 6 reaches the end of the cylinder. When the winding of the usual motor is commenced, a stud liberates a weight 30 on the shaft 27, which falls to raise the frame 31 and plate 32 and thus bring the views into their raised position. At the same time, through a link 48, the reproducer 6 is raised, and an edge 53 is lowered into engagement with a screw 40, by which the apparatus is restored to its starting condition and the plate 32 lowered into the position shown. The liberation of a pawl once more starts the apparatus.

Abstract: 15,766. Sutton, G. W. Aug. 3. Drying tea &c.-A rotary apparatus for drying or withering tea or other material is shown in Figs. 1 and 3. The drying-cylinder e rests on, and is rotated by, two pairs of suitably-driven rollers s which are journalled in a tilting frame a. The cylinder is formed with hollow wheel-shaped ends i, i<1> connected by two concentric series of heating-tubes j, k so that steam or other heating- medium can be introduced at one end through a pipe w and, after passing through the cylinder, can emerge through a combined exhaust and draining pipe x. A fan u drives air through a steamheated nest of pipes v, and the air so heated passes into, and then escapes from, an inner segmental cylinder h. The moist tea is introduced through a feed cone z, and is agitated by gills or scoops l on the outer heating-pipes, while the rate of passing through the cylinder is regulated by altering the inclination of the cylinder by means of a hand-wheel and screw. Partitions y in the end i<1> cause condensation water to pass into the draining-pipe.
